Illinois, .have invented new and useful: Im-

provements in Anticreepers with Pin-Locks, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification. V

My invention relates to improvements in anti-creepers and more particularly to looking means for maintaining the parts in their most: effective position for gripping the rail base.

For the purpose of disclosing the features of the invention, 1 have illustrated the locking means in conjunction witha two piece anti-creeper, parts of which have wedging engagement with each other beneaththe rail base.

The object of the invention 'is to provide improved locking means for a rail anchor of this general type, and more particularly, means which cannot work loose or be. accidentally withdrawn;

Figure 1 of the drawings is a top plan view of a rail anchor, which embodies one form'ofthe invention. Fig; 2 is an elevation thereof, partly in section; Fig; 3 is a section onthe line 33 of Fig. 2; Fig. 4: is a'bottom view of part of the anchor. Fig 5 isa par-. tial sectional elevation of a modified struc-- ture. Fig. 6 a similarview .of a further modification. 1 K

The rail anchor comprises two parts, the larger of which, 1, may be called the clip,

and the smaller of which, 2, may be called the mate. The clip and themate are each provided with suitably reinforced jaws 8, 3] of customary configuration,which are adapt ed to firmly grip the rail base.v The clip is providedwith arecess or groove in its upper face, one wall of which is formed by an up wardly inclined rib 4, the mate beingprovided with a downwardly inclined rib 5, the inner faces of saidribs engaging each other to lock the parts against separation. The meeting faces or walls are inclined'somewhat from a vertical plane to interlock the parts firmly against vertical separation, and are also arranged somewhat dlagonally with rei spect to the longitudinal axis of the rail,

whereby as the mate is driven forward, the jaws'33 approach each other and grip the rail base 6 firmly. The forward movement of the clip 1 is resisted by the usual crosstie 7' against which the downwardly extending bearing face 8 abuts in the usual manner. v

The inclined wall'5 of' the mate is not of the same vertical height throughout its length, but decreases in height from front to rearasshown in Fig. 3, thus providing a wedging surface 9 which slopes upwardly with respect to the base of the rail; In'order" to hold the mate against any rearward movement 'afterit has been driven forward as far as possible, a locking pin 10 is driven through a pair of alined openings'll, 12, in the clip, said pin being thrust against the wedging surface 9, thereby forming a positive lock. The pin, which may be'made of malleable iron or other. material adapted to bend without breaking, is driven into the hole as far as it will go after the clip and the mate have been driven onto the rail to their most effective gripping posit-ion. The pin is circular in cross section except that it is gradually cut away from near one end to the other, giving it a considerable taperand providing a fiat upper surface. The circular I portion conforms to the walls of the openings ll, 12 (see Fig. 3), the lower parts of which are connected so that the pin has a bearing area of considerable length beneath the pointwhere it engages the wedging surface 9 (see Fig. 2). A deflecting w'all'or abutment 13 is provided in the path of said pin causing it to be deflected downwardly as it is being driven into position, as shown in Fig. 2. The wall of said deflector which is first engaged by said pin, is sodisposed as to impart a slight twisting tendency thereto as the flat upper surface of the pin rides over said deflector. This twistingis aided by the fact that said pin is not driven in adirection exactly at right angles to the axis of the rail and hence to the edge of'the' deflec-v tor. which is parallel thereto, but is driven in at a slight angle as shownin Figs. 1 and 4. The action of the pin. is not only to lock the parts against loosening, butit even, results in tending to cause a further tightening thereof due to the fact thatit tends todraw the clip downwardly away fromthe mate i which separationis resisted by the under cut are formedmove in a proper direction either horizontally or vertically. The twisting" of the pin further increases the, security of the engagement as the fiat uppersurface thereof is crowded more firmly against the wedging surface 9. The pin being bent is prevented from working loose or being accidentally withdrawn although it may be withdrawn if occasion demands by using sufficient force;

for example, a claw-bar'may be applied to the head of the pin at thesideof the rail.

' anchor and the vpin withdrawn during which withdrawal it is automatically straightened to 'a, greater or less extent.

5 In'the modification shown in Fig. 5, theopenings 14,15 through which the pin is' drivenare fn'ot in exact alinement, one being horizontal and theother inclined downv ward l y as shown; The pin is, therefore, de-

flecteddownwardly by engaging the upper which it passes. 7

" inclinedwall of the second opening, through relative. movement of the clip and mate in 3Q, su eh a direction, as. to cause a loosen ng; of

their grip onsthe rail base. However, no obstruction is offered to a relat ve movein, such a. direction as to increase such. gripping action, 'Accor'dingly, ifthe thrust 4=. of the rail should cause a slight forward movement of the inate, the result will bean; increased gripping of the rail base by the jaws, the'leclringpin interfering in no wlse withgthisaction. Saidpin may perhaps be 4;, driven in a little farther after such a read justment, in order tobetter lock the parts in their l fin'alt position,'j any permissible move} Inent, either ofithe mate or of the'pin, however, being in such a a d rection. as a to insure 9,,greater. security rather than dlm nlsh security i Itjwill thus be seen that'the mate] maybe locked in anypos tion ofadjustinent,
